To all whom t may concern Be it known that lV Ln ROY lin'roHUM,

acitizen of the United States, and'resident of 'Brilgep `rt, in the county et Faireld end State or' Connecticut, has invented certitin new :ind useful improvements in Swivels, ot which the .following is e specilication. Y

The object of the present inventionis to provide a novel swivel of entremelysirnple construction and practical design which can be quickly, readily yand accurately `adjusted with niiniini'ini of eort, and whichwill beeapable of reliably and elliciently functioning to perforin all of the services for which vswivels are universally used.

With the above and other objects in view, the construction, arrangement and concibination et parts which constitute the 'iniproved swivel will now be fully described an; will hereinafter be speciiically claimed.`

T he improved swivel ot this invention comprises', broadly, a base, designated geneially'by nuineral 10, a holder 11 rotatably adiustable on the base and adapted to be locked to the basey in any desired lposition of adiustrnent, and vnieans ior'loclingthe base end holder to eechother ywhen the holderhes been rotated to the desired an-` nivler `adjustment on the base. The base is adapted to be secured to e. work table, l U

'Fips` 1 and 2, the under 'ofthe base is cored out, asindiceted byi in Fig. 2, to

carriage, or other support in any desired n'ianner, as bynieans ot the Slots designated 12, `end the helder is adapted to rigidly cnrrv a device or `article with which or upon which work is to be done.. rThe device or article. such, for example, as tool carryf inoinieiiiber or a vise` may be secured to the upper tice otthe holder in any ordinary er niferred manner. As shown, the holder is provided with Ways; designated generally forms disclosed lying in beveled; `adapted to rotatably and slidfiblyv receive 13, and with a three led opening 14: for the purpose of securing` the device or article.

More specilieiilly, the swivel invented by Ineconsists ol :i base having beveled, circumferential face and also havingan opening which is coi'icentiicelly arranged with respect to said beveled, circumferential face, e holder having a correspondingly beveled, circumferential face adapted to engagingly tit and to be bound to the beveled cir-'cunierential :tace of *he base, the holder being also irovided with a threaded stud, vor

equivalent nieinber, `adapted to be rotatably and slidably receiedby' the openingfin the bese, and locking nieans comprising en internally threaded engage the'thread ot theistud, or equivalent rneinber, of theholder to bind the bese` and holder to each other. The holder and hand wheel-'ot both forms Vet the invention may be identical, the dillerence between the tWo the construction et the base.

-The holder, as very clearly Adisclosed in Figs. 2 and Ll, is recessed on its under side, as indicated rby numeral 15, to provide e. bemeled` circumferential `tace 16, and er- .tending frein the/under .tace et the holder and arranged concentrically in the'recess isa stud 17 of 'considerablediameter. 18

Vdenotes a thread onthe lower portion of the stud.

Threaded opening 14, hereinbeiore mentioned, is; preferably arranged in the stud,v as shown, and the stud is preferably, though not necessarily, integral with the holder. rllhe base, in both ofthe tfoinfis disclosed, is provided with e beveled, ciro'uinferential face adapted 'to be engaged by beveled, circuiiillerentielV` fece 16 of 'the holder, and with en opening 2O which is arranged `conce'ntiically with respect to circumferential face` 19' and` is stud 17. M v

"ln the JEcrin oli the inventiondisclosed in ed portion can extend into the vcored out portion er'the bese in position yto be engaged by the internal thread, desig'nated, of the hand wheel.V @ne lower side edge or' the hand A wheel edaptcd te icc 'Y videdL with a plurality of radial'openings `25 which extend inwardly from its circumference. A short rod 26 is for Vthe purpose of succeesivelyV entering the vradial openings, and the cut away portion, designated 94, is fol the purpose of'allowing the rod to be manipulated Vtoturn the hand wheel on the threaded portion of the stud.

'In the forni of the invention disclosed in Figs. 8 and. el, the base is cored out mediate its topV and bottoni, as indicated by 27 in Fig. 1l, toi'eceive the hand wheel, and a cut away portion 28, for the saine purpose as is cut away portion 2s, is ar l in one side edge'of the base and cof mi vcates with cored out portion 27 as shown very clearlyfin Fig. il.

The cored out portion in either case may be ofV any desiredVVV configuration to. allow Vrotation Aof the hand wheel. In the formof the invention disclosed in F 'i and Q, a bearing surface 29 provided in the base is adapted toV be firmly engaged by the hand wheel when rotated to draw the holderltowardthe base.l `Vhen the hand whecA is Yrotated in opposite direction, the table, 'car- Y`priage, or other supportfurnishes the bearing .To this end, thephand wheel is of surface. Va thiclriies`sf-buty a trifle less than the distance of bearing surface29 ifrom the support for ,the base. Referring to the niodiiied forni of base, bearing surfaces 30 and 3l function exactly, as do bearing surface 29 and the support, respectively, Y

In order that angular ,adjustments of the holderv may be accurate, graduations 32, preferably denoting degrees, are suitably placed on the lower, outer edge ofthe hold` er, see` Figs. l, 3 and 5, and an'. indicating mark 33 is placed in any suitable position Von the edgerof the base to cooperate with the fgraduations. In Fig; l the indicating niark is shown placed yabove the cut away portion of the base. In Figoit is lshown' opposite the-,cut away portion.v y i The method of using the swivel `will be 'obvious 4Then the parts are assembled as shown in theV drawing and it is desired to malte an angular adjustment of thev holder,

the `rod is'inserted in a radial opening of the handfwheeland actuated vfor the length, or

la` portion of the length, of the cut awayV portion to rotate the hand wheel toelevate-the vstud and thus move the holder a sliglitrdistancev from the base so thatV the beveled,

circumferential faces of the holder and base', respectively, will be disengaged. Durving this actuationof the manipulating rod, .the handwheelof Figs. l and 2 is resting on the table as bearing surface, while the hand wheel of Figs. 3 and 4 is supported by lia-ving said stud, and upper and lower comprising ineavoe bearing surface 3i. In view of the'fact that inthe base, the holder can be turned on the base when the beveled faces of the holder and base disengaged, and by means of the graduations and indicatinor niark the proper adjustment can be accurately made. As theholdernisturned to make the adjustment, the hand wheel turns with the stud, as will he understood. then beiturnethby means of the rod, in opposite direction. The bearing surface 29 in l andZ and the bearing surface 3() in Figs. 3 and e will then he iirmly engaged by the hand wheel, and the stud will., be drawn iownwardiyr so that ythe beveled, circumferential faces of the holder and base become firmly bound to each other to lock the holderv to the base. llut a slight movenient of the manipulating rod is necessary to release or lock thev holder, and eachtime the holder and base are bound together, the

beveled, circumferential,faces engage each other in precisely the same manner, so that the distance hetweena locked holder and the supper 1 for the' base will not vary.

By providing thebase and holder, respectively, with beveled faces whicli'are adapted to engage each other as shown andY described, it is possible to located the holder close to the support for the base, and thus preclude vibration of the device orV article caiied hy the holder and with which or upon whichv work is to be done.

lt will be seenV that the swivel. can be duiclrly 'and easily manipulated.
